HC12 SI4463 Wireless Serial Port Communication ModuleThe HC 12 is the easiest way to transfer data over the air between two Arduino. Just connect the RX and TX pins for the transfer of data. It is a 100mw multi channel wireless transceiver you can use in your projects to transmit and receive serial information. HC 12 module has a microcontroller that actually doesnt have to be programmed by the user. For configuring the module we simply use AT commands, which can be sent from an Arduino, a PC, or any
